Twist Insertion

The new spinning systems clearly avoid the limitations produced by the twist insertion mechanism. It is possible to increase the twist insertion rate and the yarn production speed quite considerable. This increase is shown in the following:

Spinning System Actual twist inserting rate (rpm) The system is limited by
Twist insertion rate Doffing & transport
Ring 15,000-24,000 Yes No
Wrap 25,000-35,000 Yes No
Rotor 80,000-1,50,000 Yes Partly
Air-Jet 1,50,000-2,50,000 No Yes
Friction 2,00,000-3,00,000 No Yes
